logis {CUB} | R Documentation |
Create a matrix YY binding array Y
with a vector of ones, placed as the first column of YY.
It applies the logistic transform componentwise to the standard matrix multiplication between YY and param
.
logis(Y,param)
Y |
A generic matrix or one dimensional array |
param |
Vector of coefficients, whose length is NCOL(Y) + 1 (to consider also an intercept term) |
Return a vector whose length is NROW(Y) and whose i-th component is the logistic function
at the scalar product between the i-th row of YY and the vector param
.
